Impressive Split Dice by Tora Magic
Great VISUAL magic! Show a giant die resting on a pedestal. Place a cover over the die, remove the cover, & the die has changed color! Show the inside of the cover to be empty. Repeat this several times, each time magically changing the die to another color! When the cover is placed & removed the final time, it is found that the large die has turned into 8 smaller dice, which you can stack into piles.
